After our post yesterday we received a response on Facebook commenting on the .22LR and a conversion kit for the AR. You may recall our post yesterday was about firearms to have in the event of an extended emergency situation. While very true with the AR one could swap out the upper and carry extra magazines I think it would be better to have a dedicated .22LR long gun if that is something you want to have in your emergency supplies. It would be bad enough in the situation carrying around rifle and handgun magazines so adding more to the mix might not be the best idea. Most people would gravitate to the Ruger 10-22 as the rifle of choice, but again it is more magazines to keep up with and carry. Sure you can get double 25 mags, but the magazine is bulky and still has to be switched end over end. I would suggest you look at a Marlin Model 60. It has a tubular magazine and pre-1980s would hold at least 17 rounds and some sources say 18. In the late 80s the capacity dropped to 14, but that would be plenty of rounds for hunting small game or shooting at longer distances. The .22LR is a dirty cartridge so if for some reason in the event of an extended emergency you are shooting hundred of rounds cleaning would eventually be necessary, but most of the action was not meant to be taken apart for cleaning so no worries if you cannot get every nook and cranny. A good used Model 60 should set you back $125 if you can find one, while brand new the price will often be $175 or less. Carrying two rifles, one shotgun, two semi-automatics, and one revolver would be a chore if moving on foot, but with the post yesterday and the one today you have my suggestions for the firearms to have in an extended emergency situation to achieve the maximum standardization of cartridges and magazines. You would be able to chamber and fire .22LR, .223, 5.56, 12 gauge, .38 Special, .357 Magnum, 9mm, and .45 Auto. As those are the most popular cartridges and shot shells in the US you should be all set. As always if anything was missed or overlooked please let us know!
